Application filed December 7, 1907. Serial No. $65,522.

To all whom it may concern:

Be it known that we, (iUADALUPE Bun-1.1m and .Xururu llhC-CARI) lhusox. citizens of the United States, residing at Santa Barbara,

in the county of Santa Barbara and State of California, have invented new and useful Improvements in Stylus-Rcplenishing Mechanism for Tallting-ll/iachines, of which the following is a specification.

This invention relates to a stylus replenishing mechanism and particularly to such mechanisms for use in connection with talking machines employing disk records...

An object of this invention is to provide a device for this purpose, in which the stylus of a sound box is caused to be ejected from the stylus holder, and a new stylus inserted in its stead by suitable stylus setting mechanism. V

A further objectof this invention is to supply such stylus setting mechanism. with a fresh stylus whenever the stylus supplied thereto has been delivered to and inserted in the stylus holder, and to so arrange such mechanism that the various functionseof the -1necl1anism for carrying out these objects are performed in predetermined succession, all of such mechanism being controlled by the mere movement of the carrier arm for the sound box of a talking machine.

With these and other objects, not specifically mentioned herein, in view, this invention consists in the features, details of construction, and combination of parts, as will be described in connection with the accompanying drawings, and then be more specifically pointed out in the claims.

I11 the drawings: Figure 1 is a side elevation of our improved replenishing device, showing the same attached for operation to a. talking machine; partsof the. view are broken to contract the same. Fig 2 is a front elevation. Fig. 3 is 'a side elevation showing the device attached to a talking machine (the sound box being shown in fragment) and proper mechanism for adapting the replenishing mechanism to such machines known as the Zonophone or Victor. Fig. 4 is a frontelevation showing the application of the replenishing mechanism to a Columbia talking machine. FigI 5 is a side elevation looking to left of Fig. 4. Fig. (I is a side elevation showing the application of the replenishing mechanism to a Zonophone or such machines in which the sound boxes are provided with screws for .the threads 8 of the post clamping the stylus. Fig. 7 is a fragmentary side elevation showing the stylus setter in the act of delivering a stylus to the stylusholdcr. Fig. 8 is a fragmentary sectional detail of stylus retaining mechanism for Zonophones. Fig. 9 is a detail of the stylus retaining toothed wheel and spring Fig. 10 is a perspective view, illustrating the mechanism for actuating the stylus clamp to release a. used stylus, preparatory to inserting another, the dotted lines indicating the active, and the full lines, the passive position of such mechanism. Fig 11 is a detail sectional view of the trackway and ca riage. Fig. 12 is a detail of the link for controlling the stylus releasing mechanism.

,Fig. 13 is a detail of the lever for releasing the stylus from frictional hold in the stylus holder. Fig. 14 is a detail of a funnel arranged to be fitted on the stylus holder of a Zonophone sound box. Fig. '15 is a detail plan of the spring arranged to hold the disk A of the magazine in place. Fig. 1G is a fragmental detail showing position of mechanism for releasing the stylus from the stylus holder, before the actuation thereof.

Fig. 17 is a similar view showing the stylus releasing mechanism in position to cause the stylus to drop from the stylus holder. Fig. 18 is a plan view of one of the maga zine disks, and Fig. 19 is a plan view of the platform, showing the opening in therdelivery chute, the magazine proper being 'oinitted.

1 designates the motor containing receptacle of'the ordinary talking machine. '2 is a support in the nature of an arm removably attached to said motor containing receptacle. 3 is av sound box carrier arm swiveled, or otherwise attached and movable relatively to said sumnorting arm 2. sound box carried by said carrier arm Mounted on and detachably secured to said supporting arm 2 is a furcated post 5, the tines (S of which straddle the supporting arm 2 and are provided with elongated slots 7 for the accommodation. of set screws, or other fastening means not shown. The upper terminus of said post is externally screw threaded, as seen at 8 and provided with a central'bore 9, shown in dotted lines.

10 is an adjusting nut adapted to ,cngage Said nut is unit-ednvith a sleeve 11 having a threaded central bore, the said sleeve having integrally united therewith a thumb piece 12, by

.ceive a lever 37' 'tion, and also to means of which the adjustment of the nut 43 is a disk like is effected.

13 is a bearing on said thumb piece 12 for the shoulder 14 of the member 15, which is provided with a shank 16, extending within the bore 9 of the post 5. The said member 15 is provided with an aperture 17 rectangular in cross section to receive a bar 18 in which aperture the said arm is secured by the set screw 19. The bar 18 terminates in a hollow sleeve 20 into the bore 21 of which is fitted a bent supporting arm 22, which terminates in a tang 23. One end of the bent supporting arm is screw threaded as seen at 24, and designates aset nut whichengages the threads 24 of the said supporting arm 22.

'26 is a washer interposed between the nut 25 and the upper end of the sleeve 20.

By .the mechanism thus far described, it

will be seen that the distance of the bar 18 from the surface of the record 27 is capable of regulation to render the mechanism to be presently made the subject of more detailed description, susceptible of use with all talking machines of the disk type, where variations. in mechanical construction are not in frequently present.

28 is a strap adapted to encircle the sound box carrier arm 3. This strap 28 terminates on one end in a screw threaded shank 29 and on the other end in a cup- 30, which is provided with an orifice 31. The shank 29 is arranged to extend through the orifice 31 of thecup and there to be engaged by a thumb nut 32, which is adapted to tighten ,the strap on the sound box carrying arm of "the talking machine. 33 designates a short post provided on the strap 28.

34 is an arm provided-with a sleeve 35, having a screw threaded opening 36 to reby the manipulation of which the arm 34 is locked in any position of adjustment. This arm 34 terminates in a loop 38 which fits over a tube 39. '40 designates a screw for preventing the accidental movement of said tube relatively to the arm 34. Fitting over the tube 39 is a magazine 41, consisting of two separated disks A and B, each of which is provided with a circumferential row of perforations C which perforations in the respective disks A and B are out of perpendicular alinement relatively to each other, so that a stylus extending through the perforations of both disks stands at an angle to the vertical axis of the tube 39 as seen in Figs. 23-45 and 6. The disk B is provided on its under surface with an annular rack.42. 40 designates a set screw extending through a slot 40 provided in the platform 43 under the magazine disk 3 and arranged to secure the carriage and trackway on the arm 34 and against rotapermit of the adjustment of the same to adapt it to varying angles.

93. ,eve'

a part of said tube dished as seen at 44 Fig. .19 and has an upturned peripheral edge whose function is to prevent the. stylus from'escaping fromthe magazine.

The tube 39 above referred to terminates in a bifurcation 46-, which forms'substantially a carriage, the said bifurcation. 46 being provided with rails 47. 48 is a trackway, having grooves 49 arranged to engage said rails 47 and ride thereon. The said trackw'ay is slotted centrally thereof as seen at 50 to receive a plunger 51, whoselupper end extends into tube 39; The plunger 51 is normally connected with said trackway, to have contemporaneous movement therewith, by a crank 52 pivoted to said carriage at 53. A spring D is coiled about the shank of the pivot 53, which spring exerts its tension against the crank, thereby causing the platform, secured or made 39. This platform is crank to frictionally bear against the head the vibratory action of the stylus while traversing the sound waves of the record. The crank 52 is provided with a detent 54 on one side to engage the pin 55 fixed on the plunger 51 whereby the trackway andplurrger are mutually interlocked. A similar detent 56 is provided on the opposite side of said crank 52 to engage a pin 57 provided o the bifurcation 46, for normally holding igie crank out of operative position. In this p sition of the crank that is to say, when the detent .56 is in engagement with the pin 5' the plunger is free to move independentl of the trackway 48, which provision is made for the purpose of permitting of the' movement of the carrier arm for the sound box, plenishing The plunger into which the tang 23 of the supporting arm'22 is arranged tofit and to be secured therein. In this manner it will be noted that the trackway 48 is stationary relatively mechanism for the sound box.

is rigidly attached to the sound-' 59 is a spiral spring located within the bore of the tube 39 and arranged to impinge against the collar 60 fixed on to the plunger 51. The tube 39 at its upper extremity is internally threaded asseen at 6]. to, receive the shank 62 of an adjusting member (3-3.

By this construction the carriage and the 2 magazine etc. are resiliently summrted on the plunger 51 and the height and the movement of the carriage and sound box rela- 7 of said lever is pivoted by a nivot pin ('38, a

pawl (39, having free movement in one direction, but a limited movement in another direction. For this purpose the end of the pawl is extended as seen at T0 and so arranged that it is in direct line with the fulcrunr pin 67 of the lever (36. Thus upon the ope *ation of the lever (36, the fulcrum pin 67 strikes the extended portion 70 of the pawl and causes said pawl G9 to travel with said lever. Both lever (36 and pawl 69 exten d through an opening provided therefor in the platform l3, the said pawl 69 being in direct line and in engagement with the annular gear face 42 provided on the underside of the disk B forming part of the megazine 41. Upon the operation therefore of the lever 66, the pawl (59 moving therewith, produces a rotation of the magazine ll, equal to one tooth in the annular gear face -'l'2.'

The end of the lever 66 is weighted as seen at 71, ,so that upon the recession of the mechanism for operating said lever (36, the said lever by gravity drops back to its normal position, carrying with it the pawl CS) which having an operating tendency in but one direction, rides over the teeth of the an nular gear face at, preparatory to the succeeding operation of the lever for rotating said for.

.To the platform 4?) is attached a tube, or more properly, a delivery chute T2. the entrance to the' bore of which is located at or causes a near the outer periphery of'the same, as seen.

at. '73, and in a direct line with the points of v the styli with which the magazine ll supplied. The rotation, therefore, of the said stylus magazine for a distance equal to one. tooth of the gear face l") on the disk I). stylus at each such predetermined rotation of the magazine. t e enter the delivery chute 72. From this chute it discharged into a stylus setter 7i hingedly hung from a pintle 75, which extends through a sleeve 74') provided on a crank arm 77. The crank arm 77 i secured to a 1ft T9, the. said crank arm being provided with a strap 79, which is provided with a lug 50 for pur poses to be more fully hereinafter set forth. The said shaft 78 extends througi'i a sleeve 81, which is fixedly secured to a boss 82,

magazine. to cause a fresh stylus to drop and travel in the chute provided theremade integral with the earriage. This shaft '78 has mounted on one end of the same a mutilated pinion 83, being provided for a portion only of its peripheral circumference with teeth. This pinion Sb is in direct line with a rack 84, rigidly fastened to the trackway l8, and arranged to remain stationary during the movement of the carriage it), whic'ii movement, as the rack engages the pinion. causes the shaft 78 to revolve and at the s'inne' time carry with it the stylus setter carried thereby, which stylus setter, describing the arc of a circle, brings the stylus in direct line with the opening in the stylus holder wherein it is thereupon clamped. ()n the strap T9 is a pivot for pivoting a lever 86, one end of which is designed to extend -in the rear of the stylus and the other end of which extends over and in direct line with the lug 80, this said other end being heavier, so that gravity normally holds the said lever in position. The heavier part of this lever has a Shoulder 88. The travel o the stylus setter to deliver a fresh stylus into the stylus holder in the sound box. causes the lug 80 on the strap of the stylus setter to strike against said shoulder 88 and in this manner to actuate said lever so that it is brought to bear against the rear of the styais thereby causing it to be released from its frictional hold and to escape from the stylus holder. ihe said boss 82 has united therewith an arm 89 terminating in a pivot 90 and also provided with a yoke 91. Pivoted to the pivot 90 a bell crank lever 92, one arm of which, namely 95. is arranged to ex tend in operative relation to the resilient jaws of the stylus holder 94, where such stylus holding mechanism is employed; the other end of said bell crank lever 92 extends between the yoke 91 and curves downwardly toward itsv end as seen at no, where it terminates in a shelf 9%).

()n the carriage 48 is pivotally mounted by the pivot a link 101, provided with an adjustable set screw 102 and with an abrupt shoulder portion 103, shown in dotted lines in Fig. 10. This shouldered portion 103 is normally in engagement with the extremity of the arm )5 of the lever 02 so that the movement of the carriage relatively to the trackway causes said arm J5 of the lever 9; to turn on its pivot ill) and thereby exert pressure against the jaws-of the stylus holder, thus relieving the tension and allowing the stylus to fall. The continned elevation of the tack' 'ay carrying with it the bell crank lever 92 carries the link 101 with it until it approaches a horizontal position where the set screw 10 2 strik s the slielflli and removes the pressure of the arnrtli of the bell crank lever 92 from the clamping stylus holder 94 the moment that the stylus is nserted in the stylus holder, thus causing it to he clamped while "the bell crank lever and resets it preparaan abutmentlOat whereby the magazine is is the aforesaid opening or orifice 111 which is fixed to said shoulder 113, and the at the same time the action of the spring, assuming its normal position,- bears against tory t0 the next operation.

In order to accomplish the setting of the ylus in the stylus holder, an upward movement of the trackway relatively to the carriage is necessary. Upon the return movement of the carriage relative to the trackway, the weighted lever 71 strikes against caused to travel a distance equal to one tooth of the annular gear face 42 provided on the disk B.

The mechanism thus far described, which relates to the means for'releasing a used stylus, is applicable to such machines known as the Columbia and Victor talking machine, in which resilient means, specifically a* spring, are employed to clamp the stylus in place, and to all sound boxes employing a lever to clamp the stylus.

In order torender the replenishing mechanism susceptible of use with machines known as the zonophone or Victor with sound boxes employing a screw to clamp the stylus, we have made the following provisioni- On the chute 72, is a shelf 105 made integral with a socket 106arrangedto be detachably fitted over the end of the chute 72,. and to be secured in place by screw 107. 109 designates a funnel or guide arranged to frictionally enga e the end of the stylus holder 108. 'Said Emnel is provided with an orifice 111 which when in place registers exactly with the opening in the stylus holder 108.v It is also provided with a curved face 110 at the center of the curvature of-which through which the stylus is arranged to extend. i This curved face is designed to prevent the stylus from missing the opening in the funnel when the stylus setter traverses the distance from the chute end to the stylus holder, The new stylus, when by reason of any defective adjustment of the stylus setter, strikes against the curved face, and is caused in this manner to enter the orifice or opening 111' of the curved face 110; Extending'through the stylus holder 108 is a screw threaded shankllQ provided with a shoulder 113 arranged to bear against the stylus holder 108. Around this shoulder portion is coiled a spring 114 one end of other. end of which is fixed to the stylus holder 1.08. A toothed wheel 115 is integrally united with the shoulder portion 113.

purpose of permitting the screw threaded shank to rotate but for a limited extent when the stylus holderis not supplied with a stylus, which limited rotation however is suilicient' to clamp an inverted stylus' Adapted to be thrown into engagement with another.

said toothed wheel 115 is a rack 116, made a part of an inverted U-shaped member 117, which is pivotally mounted bn an arm 118, removably fitting into an opening 119 pro-. vided in the rack 84:- of the carriage. The 79 tine 120 of the inverted U-shaped member 117 has an adjusting screw 121, which upon the operation of the carriage relative to the trackway strikes against the shelf 1G5, thereby causing the rackllfi to engage the toothed wheel 115 for a predetermined period sufficient to actuate the toothed wheel to release the used stylus and allow a fresh, stylus to be inserted, Whereupon'the adjusting screw clearing the shelf 105-causes the g immediate disengagement of the rack with the toothed wheel 115, which by reason of the sprin clamps the new stylus in the stylus hol er.
